To all whom it may concern:

Be it known that I, GEORGE A. SEELY,

citizen of the United States, residing in thecity and county of San Francisco and State tected against injury by the vibration of .the piece when discharged. i

he -invention consists of the parts" and the construction and combination of parts as hereinafter more fully described and claimed, reference to the accompanying drawings, in which Figure 1 is a partial side view of a gun partly insection with the illuminating sight in position Fig. 251s a cross section on line XX. Fig.1. Fig. 3 is an enlarged view of the sight. Fig. 4 is a detail showing the yieldable socket. Fig. 5 is a longitudinal sectional view of a modified form ofsight structure. Fig. 6 is'a cross section of the socket structure and tube. Fig. 7 is a front elevation of the lamp.

ing 9 and cap 12 and extends into the gun- .stock 13 where it engages a contact piece 14 engageable by a push-pin 15 mounted in and adjacent to the end ofthe gun-stock. The contact-piece, 14, is connected by a w1re or appropriate conductor 16 to an'electric battery 17 arranged in a chamber 18. in the gun-stock butt.

If several cells are employed in the bat- D tery, they are forced into contact by a spring 19 to which is connectedconductor It, the innermost battery contacting 'w1th a wire 20 In the illustrated embodiment of the derunning through the gun-stock and'grounding current by contact with the metal work. Thus a circuit will include'the tube 2 and its bushing 9, the gun-barrel, the ground wire 20, spring 19, the batteries and thence through the conductor 16 to switch 15.

When the switch is operated it sends current from contact piece 14 and wire 11 to the socket 10, saidfsockets being electrically connected to the bushing, 9, by a flexible device, as wire, 9.

. A very important feature of my invention is the provision of a structure designed to guard the small electric bulb'21 in socket 10 against destruction by the shock of the gun when discharged. This safe guard comprises a tubular bearing or shell 22, insulated from and secured in the bushing 9 in which the socket 10 may'move axially but not circumferentially; the latter movement being prevented by a rib or flange 23 there- '.on fitting a channel 24 in the shell 22.

- The socket is yieldably connected to the back of the. bushing by a coil 24: connected to the conductor'll, and the outer end of the socket is connected by a wire 11 of one 1 or more turns to the bushing and thus completing an electric circuit with the tube 2. By preventing the socket from turning in the shell 22a bulb can easily be screwed in and there is no danger of the lamp filament 25 being destroyedby shock because of the spring or yielding element 24.

Preferably the filament 25 is made circular in plan, as in Fig. 7, and inorder to obtain the maximum efiiciency from the light,

I form a series of threaded holes 26 in the circumference of the bushing so that this may be turned or adjusted to best concentrate the rays of light and then fastened by a screw 27 projecting through a slot 28 in the tube 2. The slot permits the bushing to '-be adjusted to or from the'lens as may be required. A modified form of the invention includes a tube 30 of sufiicient length to con tain a series of battery cells 31, against one of which acts a coil 32 having a plate 33 seated against an insulating block 34. This block fits thetube and contains a spring 35 effectiveto force a button 36 outwardly. The button projects through a ca 37 on the end of the tube and, when pressed, closes an electric circuit from the cells 31, coil 32 to the tube 30. The front end of the tube is provided with a lens 38 and located in rear connected to the lamp, and a coneluding a. tube, means for adjusting itu on a firearm, a lens in said tube, a circu erentially adjustable bushing mounted in the tube and having a yieldable lamp and socket,

a source of electricity'related to the socket and bushing, and a switch controlling the energization of the lamp.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE A. SEELY.
